deathmetal5150 Posted March 3, 2005 Report Posted March 3, 2005 hi everyone interested in finding out more about these cylinders. im told you can bolt these on and have some pretty good results. however, wondering about the reliability? i see that they have nikasil involved, can you give me a run down on this? basically im interested in getting them for aggressive play riding, but want reliability to be top priority. how often do you have to change pistons, also how about the rings ? any info is appreciated.

01bansheeke Posted March 3, 2005 Report Posted March 3, 2005 yes they are nikasil plated. they are drag cylinder. Unless you haul wide open all the time, you prolly don't want them. JMO My cheetah cub motor will be up and running next weekend. I'l let you know how it runs. I think on average you can run 175 gallons of fuel through them before a rebuild. That would only involve new pistons/rings. NOt a bore like a typical motor. however, if you shell a crank etc and you tear up the nikasil. It is not cheap to have replated. Quote
deathmetal5150 Posted March 3, 2005 Author Report Posted March 3, 2005 ive heard a couple people say that they're ok for trail riding and racing around on, however i heard a few people say you just want these for strictly racing. why is that? interested in hearing about it. wonder if its because maybe they will overheat easily or just wheelspin is pretty rough?

01bansheeke Posted March 3, 2005 Report Posted March 3, 2005 wheelspin would definitley be out of control. The port work/etc is set up for drag racing. not really a trail/play cylinder. I guess you could use it for that, but you wouldn't be using its full potential by any means. Quote
deathmetal5150 Posted March 3, 2005 Author Report Posted March 3, 2005 i know that they have different port options, i was wondering if one were to go with the bottom line cub setup without all that stage porting, if it would be ok then? Quote
1800bigk Posted March 3, 2005 Report Posted March 3, 2005 I have the big cheetah 4 mil and I trail ride all the time. It makes the banshee so much more fun to ride now because of the low end power. It has as much low end as my yfz 450 maybe more. Wheelspin is not any more noticable then when I had ported stock jugs. In fact when I had ported stock jugs my powerband was like an on/off switch so it was not fun in the woods. Now I can lug it around like a 4 stroke. It runs hella cooler and has amazing top end.

deathmetal5150 Posted March 3, 2005 Author Report Posted March 3, 2005 thats what i was lookin to hear. actually what im also wondering is, how hard are these on the crank? im wondering if the crank is going to take a beating on this and need replaced a lot more often? what do you think? Quote

deathmetal5150 Posted March 3, 2005 Author Report Posted March 3, 2005 (edited) Sounds great. So far, the only thing im not sure about yet is the ring wear and fuel economy. How often are the rings going to have to be changed? I noticed a lot of folks going by "gallons", so wondering how much difference the fuel economy is going to be from stock cylinders?

01bansheeke Posted March 3, 2005 Report Posted March 3, 2005 HOnestly, a lot of things you are worried about, it sounds like you need to go with a woods port or something like that. I spent about 1200 for the cheetah cubs with pistons, a clean up port, and shipping. Another 450 on a crank..and more than that on pipes. Not bad for the caliber motor i will have. Traded for carbs etc. Still waiting on some parts. but they will be here soon. The Casting of these cylinders is pretty much a drag port already. Most porters are only doing a clean up port on these. The only disadvantage to these that i can see so far is the lack of powervalves. But the powervalves just aren't worth the extra 2 grand + just my opinion. Plus using that bigger reed set-up is WAY over rated. Quote

01bansheeke Posted March 3, 2005 Report Posted March 3, 2005 Ohton sells them for 1000 ported and plated. The trinity kit sells for like 3500 banks. crank and all. After all the stuff i have picked up, I won't be in it for more than 2 g's. thats getting great deals on parts for the most part. plus you can get away with using your stock stuff. You don't HAVE To run the cheetah specific stuff. thats where the cub shines IMO Quote
01bansheeke Posted March 3, 2005 Report Posted March 3, 2005 um, powervalves cost $400, and thats what trinity charges, you can get them for a lot less on planetsand. A&S will sell you a ported 421 big cheetah for $1900, thats with out a crank though, crank will bring the total to $2350. A cheetah cub will cost 1200 for ported/plated cylinders, 450 for crank, and if you dont have a cool head with big bore domes and intakes for big carbs then you can add 250 for head, 100 for big intakes. which = $2000 so you can save $350 by going with the cubs and even more if you get the cubs with 65mm bore. 332808[/snapback] also, didn't necissarily realize that you could get the powervalved motors for that price./ Quote
1800bigk Posted March 3, 2005 Report Posted March 3, 2005 (edited) trinity is over priced, mine is not powervalved, but i may try them out if i get bored with this. Edited March 3, 2005 by 1800bigk Quote
01bansheeke Posted March 3, 2005 Report Posted March 3, 2005 I thought the big cheetahs were powervalved? Quote
